JOHN G'OODFELLOW, OF T-ROY, NEW YORK, ASSIGNOR TO HIMSELF AND R. S.GOODFELLOW, OF SAME PLACE.

Letters-Patent No. 100,138, dated February. 22, 1870.

The Schedule referred to in these Letters Patent and making part ofthessm To all whom it may concern Be it known that I, J our H. Goonrsnnow,of Troy,-in the county of Rensselae'r, and State of New- York, haveinvented anewan'd useful Improvement in Stoves; and I -do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilled in the art't-o make and use the same,reference being had to the accompanying drawiu, s ibrmin'g part of thisspecification, in whichiljgurc 1' is a front view of a parlor-stove towhich my improvements have been attached, parts being broken away toshow the construction. Figure 2 is a horizontal section of the same,taken through the line a: z, fig. 1. Figure 3 is a horizontal section ofthe same, taken through the line y y, fig. 1.

Figure 4 is a horizontal section of the same, taken through the'line zz, fig. '1.

Figure 5 is a detail horizontal section of the expandingfeeder, takenthrough the line 4; o, fig. 1.

My invention has for its object to improve .the construction ofheating-stoves with respect to supplyingv them with coal and with air tosupport combustion, it being designed to supply the fire-box with acurrent of heated air, whereby combustion is facilitated and an economyof fuel effected; and v It consists in the construction of the feederahdof the draught-flue as hereinafter more fully described.

Arepreseuts the base of the stove; 4

B, the upper part or cylinder; and

G, the fire-box.

.D is the expandiug'feeder, which is made in two or moreparts or pieces,the edges of which are so formed -as to overlap each other, as shown infigs. 1 and 5.

ilhe parts or pieces of the feeder D are hooked, hinged, pivoted, orotherwise suspended from the top of the stove or from thelower end of ashort feed-pipe, projecting downward from said top. I prefer to suspendthe parts of the feeder D detachabl y, so that they may be convenientlydetached and removed when desired or necessary. If desired, one or moreof the parts of the feeder D may be made stationary, and the other partsmovable. The parts of the feeder D may be pivoted otherwise than'attheir upper ends,but 1 prefer the construction first described, as beingsimpler and more convenient; By this construction of the feeder, whenthe coal placed in it expands from becoming heated, the lower part ofthe'feeder D is expanded or forced outward, to give increased room tothe coal, and s-rthat the coal will not choke up the =i'eeder, but willi-ifree to pass down to the fire-box asjit is required to supportcombustion.

The smoke and other products of combustion pass from the fire-boxG downthe flue E,at the rear of the stove, 'to the base A, where they passforward through the fine F, and back tirough the flue G to the pipe H,having parted witl' the greater part of their heat before entering saidpipe H.

The air to support combustion passes in through an opening, I, in thefront part'of the stove, above the center of the fire-box C. It thenpasses around the fire-box O, and down through an opening formed in orat the end of theflue-strip J, as showuin fig. 3, and back around thelower-part of the fire-box,- and down through an opening formed in or atthe end of theflue-strip K, into the ash-pit, whence it passes throughthe grate to the fire.

The air is made to pass down through the openings in the flue-strips'Jand K by vertical strips M and N, respectively, which cross the duesformed by-the said flue-strips J and K, and thus interrupt theonwardpassage of the air.

L is the gas-ring formed around theu er edgc'of the fire-hos 0, throughwhich air may pass into the upper part of the fire-box. By enlarging theopenings in the gas-ring L, so as to admit suflicieut air to supportcombustion, the stove maybe arranged to burn with a down draught.

The flue-strips J are so arranged as to bring the air to support thedraught-in contact with the entire surface of the fire-boX O, and detainit in contact with said fire-box until it may be entirely heated. Thefine-strips J may be formed solid ivith the firebox G, or they mayb'emade separate'and zdetachable, as may be desired or most convenient.

The-opening in the case of thestdve through which .the air enters thedues formed by the flue-strips J may be furnished with dampers, toregulate the draught of the stove, or the said draught may be regulatedby a damper placed in the. smoke-pipe.

Having thus described my invention,

I claim as new and desire to secure by Letters Paieut- The combinationof a detachable expaudingfeeder with the case and fire-box of a stove,substantially as i lerein shown and described and for the .purposesetorth.

2. The detachable expanding feeder D, constructed substantially asherein shown and described, in combination with the case or cylinder 13and fire-box O, as and for the purpose set. forth.

3. The flue-strips J, whether placed in vertical or horizontaldirections, in combination with the fire -box O and lower flue-strips orflange K, and so arranged as to receive the air to supply the draughtabove the central line of the fire-box, and conduct it one or more.times about said fire-box before it escapes'through openings in thelower flue-strips or flange K, into the ash-pit below the grate,substantially as herein shown and described and for the purpose setforth.

4. The gas-ring L, formed with an inward projection'or swell around theupper edge of the fire-box, in combination with the flue-strips J and Kand with said fire-box, substantially as herein shown and described andfortbe purpose set forth.

5. The vertical strips M and N, in combination with .theflne-strips Jand K and fire-box G and outer case B, substantially as herein shown anddescribed and for the purpose set forth.

'6. The opening 0 formed in the fine-strip K, at the front of thefire-box O, and communicating with the ash-pit, substantially as hereinshown and described and for the purpose set forth.

7. The combination of dampers placeddn the front and sides of thestove,-either or both, with the sets of line-strips J K and M N, oreither of them,substantially'as herein shown and described, to regulatethe draught of the stove, as set forth. 1
